【摘要】 对 As- Se- Te玻璃原料提纯和熔制工艺进行改进。制成具有芯包结构、阶跃折射率的红外玻璃光纤。对 As- Se- Te玻璃进行微量杂质分析。同时 ,对拉制成的 As- Se- Te玻璃红外光纤测试其损耗。结果表明 :工艺改进后 ,光纤损耗值降低与玻璃微量杂质总 (正、负 )离子计数相对比值减小是一致的更多还原

【Abstract】 Purifing of As Se Te glass raw element and melting technology were improved.As Se Te glass infrared fibers with a core cladding structure and step refractive index were fabricated.The trace impurities in As Se Te glass is measured.The loss of As Se Te glass infrared fiber is measured .It is shown that the reductions of fiber loss and reductions of relative proportionality of total ion counts were concurrent.更多还原
